Quality of will and radical value reversals
Al Mele’s Manipulated Agents: A Window to Moral Responsibility (OUP 2019) is an extraordinarily careful and clear little book. A central recurring element is the use of examples of radical value reversals due to manipulation. In this commentary, I discuss the relevance of these examples to a simple quality of will account of blameworthiness without explicit historical conditions. Such an account, I suggest, can fairly straightforwardly explain how value reversals might mitigate blameworthiness. But I also suggest that the intuition that they completely remove blameworthiness should instead be explained away
Hard diffraction -- 20 years later
The idea of diffractive processes with a hard scale involved, to resolve the
underlying parton dynamics, was published 1985 and experimentally verified
1988. Today hard diffraction is an active research field with high-quality data
and new theoretical models. The trend from Regge-based pomeron models to
QCD-based parton level models has given insights on QCD dynamics involving
perturbative gluon exchange mechanisms, including the predicted BFKL-dynamics,
as well as novel ideas on non-perturbative colour fields and their
interactions. Extrapolations to the LHC include the interesting possibility of
diffractive Higgs production.Comment: 14 pages, 19 figures. Invited talk at XXII International Symposium on

Experimental philosophy and moral responsibility
Can experimental philosophy help us answer central questions about the nature of moral responsibility, such as the question of whether moral responsibility is compatible with determinism? Specifically, can folk judgments in line with a particular answer to that question provide support for that answer. Based on reasoning familiar from Condorcet’s Jury Theorem, such support could be had if individual judges track the truth of the matter independently and with some modest reliability: such reliability quickly aggregates as the number of judges goes up. In this chapter, however, I argue, partly based on empirical evidence, that although non-specialist judgments might on average be more likely than not to get things right, their individual likelihoods fail to aggregate because they do not track truth with sufficient independence
Tracking chains revisited
The structure , introduced and first
analyzed in Carlson and Wilken 2012 (APAL), is shown to be elementary
recursive. Here, denotes the proof-theoretic ordinal of the fragment
- of second order number theory, or equivalently the
set theory , which axiomatizes limits of models of
Kripke-Platek set theory with infinity. The partial orderings and
denote the relations of - and -elementary
substructure, respectively. In a subsequent article we will show that the
structure comprises the core of the structure of pure
elementary patterns of resemblance of order . In Carlson and Wilken 2012
(APAL) the stage has been set by showing that the least ordinal containing a
cover of each pure pattern of order is . However, it is not
obvious from Carlson and Wilken 2012 (APAL) that is an elementary
recursive structure. This is shown here through a considerable disentanglement
in the description of connectivity components of and . The key
to and starting point of our analysis is the apparatus of ordinal arithmetic
developed in Wilken 2007 (APAL) and in Section 5 of Carlson and Wilken 2012
(JSL), which was enhanced in Carlson and Wilken 2012 (APAL) specifically for
the analysis of .Comment: The text was edited and aligned with reference [10], Lemma 5.11 was

Action and Ethics. A Historical Perspective on the Late Frankfurt School (Apel, Habermas, Wellmer)
I shall delineate what I see as the strength and relevance of transcendental-pragmatics within the intellectual setting in the post-war period. I shall indicate how the discussions within transcendental-pragmatics have revealed inherent challenges, while at the same time the intellectual and institutional surroundings have changed unfavorably during the last few decades. And I shall briefly indicate how these inherent challenges and new constellations could and should be met, to the effect that transcendental-pragmatics could reveal its philosophical importance and practical relevance under changed conditions; the catchword here is gradual (melioristic) reasoning
A simple and elementary proof of Whitney's unique embedding theorem
In this note we give a short and elementary proof of a more general version
of Whitney's theorem that 3-connected planar graphs have a unique embedding in
the plane. A consequence of the theorem is that cubic plane graphs cannot be
embedded in a higher genus with a simple dual. The aim of this paper is to
promote a simple and elementary proof, which is especially well suited for
lectures presenting Whitney's theorem
